to takeout apparatus for the removal of articles of glassware, such as bottles, from the final molds of bottle forming machines of the Owens type, that is, machines in 5 which the final molds open at a position in which the longer and normally vertical axis of the bottle or article being formed is at an angle to the vertical. The present invention constitutes an extension of and improvement upon the invention of my prior Patent No. 1,654,091, granted December 27, 1927, and is particularly intended to adapt the structure of this prior patent to the removal of articles from machines of the Owens type.

Among the objects of to provide a device for the present invention is the efficient removal or taking out of bottles or other articles from the final molds of a forming machine of the Owens type, that is, a machine in which the final molds are swung down about a horizontal axis to a position such that the longitudinal axis of the article to be removed from to the vertical.

the mold is at an angle A further object of the present invention is to provide apparatus of the character above set forth, in which all of the various features and adapted for use with advantages of the device of my prior patent above mentioned are included, and which is further Owens-type machines,

whether operated continuously or intermittently.

A further object of the present invention is to provide in a device of the character described a means for steadying the lower portion of an article being removed from a mold at a position in which its longitudinal axis is inclined to the vertical and preventing the distortion of that article in transferring it from this inclined position to its normal vertical position.

Further objects of my present invention include certain particular mechanisms and adjustments, allwof which will be apparent from a reading of the following specification and subjoined claims when taken in connection with the accompanying drawings, in which Figure 1 is a plan view of a takeout mechanism embodying my invention with portions of the shaping machine and the conveyor for receiving the ware from the takeout; and

Fig. 2 is an elevation of the machine of Fig. 1, certain parts being shown broken away, omitted, and/or in vertical section.

In my prior patent above referred to, there is shown and described a takeout device for removing ware from the final chine in which the tinuously about a vertic molds of a forming mafinal molds may rotate conalaxiabutinwhichthe 1932, Serial No. 631,133

final molds are permanently upright upon the mold carrier. In the well-known commercial Owens machines, the final molds are mounted upon arms pivoted to the mold carrier for movement about horizontal axes tangent to a circle, the center of which is the axis of rotation of the mold carrier. Prior to the opening of the molds, they are swung downwardly from their position in which the articles are finally blown to a position in which the longer and normally vertical axes of the articles are at an angle (sometimes inclined and sometimes substantially horizontal) to the'vertical. The usual practice in operating machines of this general type is merely to open the molds allowing the articles to fall out of them and usually down a chute where they may be manually picked up and set upright by takeout boys. In certain instances, this has caused damage to the ware due to contact of articles with each other, and also due to deformation due to the rough handling of the somewhat semiplastic ware.

The present invention provides a means for rendering the operation of removal of the articles from molds of machines of this type entirely automatic, and thus dispenses with the services of the boys used in setting up the articles, as well as preventsthe distortion or other injury to the articles incident to the manner in which they have been handled in the past.

To a major extent, the present device is constructed along the lines of the device of my prior patent, but includes in addition and in combination with the structures therein disclosed, mechanism for adapting that structure to the removal of articles such as bottles from molds positioned as are the final molds of the well known commercial Owens machine.

Referring to the drawings, there is illustrated a fragmentary portion of an Owens type of machine including a large gear 1 rigidly mounted upon the final mold carrier of the machine and in the usual case adapted for continuous rotation. Mounted in the usual way as above set forth upon the mold carrier is an arm, the end of which is shown at 2 (Fig. 2), this arm being pivoted about a horizontal axis (not shown) so that the mold 3 carried thereby may be lowered fromits final The takeout mechanism is mounted on a shaft or standard 6 slidably mounted in a bearing member '7 which may be mounted upon any suitable fixed base (not shown). The shaft 6 is prevented from turning by a spline or key 8 in the bearing member '7, thus permitting vertical movement of the shaft 6 while preventing its rotation. Rotatably mounted on the shaft 6 is a gear 9 for actuating the takeout device. The teeth of the gear 9 mesh with those of the driving gear 1 which, as above set forth, is suitably connected to the mold support of the forming machine. The takeout may, if desired, be driven by an independent mechanism. In any case, the mechanisms will be so timed as to cause successive molds and takeouts to arrive at the takeout zone or station at the same time.

The takeout implements, here shown as tongs 10, are provided with properly shaped ware engaging portions 11 designed to engage the particular type of ware being made by the shaping machine. The tongs 10 are removably secured to tong arms 12 by providing a pair of apertures in each of the tongs through which extend studs projecting upwardly from the tong arms, suitable thumb screws 13 being provided for holding the tongs in engagement with the tong arms. The tong arms 12 are pivoted at 14 to tong carrying members 15 and are closed by tension springs 16 extending between the tong arms 12. The tong carrying members 15 are pivoted to slide members 17 on horizontally disposed pintles 18. The slides 17 are each mounted between guides 19 on the outer end of the takeout arms or supports 20, the left hand arm (as seen on the drawings) being supported by a bearing 21 journaled on the shaft 6 and the right hand arm (Fig. 2) having a bearing 22 journaled on the bearing 21. The takeout arms 20 are independently revoluble relative to each other and are moved by levers 23 connected to the outer ends of the arms 20 by links 24. The levers 23 are pivotally supported upon a bracket 25 rotatably mounted upon the shaft 6, the bracket 25 being adjustably secured to the gear 9 by suitable clamp screws 26 extending through circumferentially elongated slots in the flange portion 27 of the bracket.

Interposed between the takeout arms 20 and the levers 23 is a stationary cam member 28, secured to the shaft 6 in any desired manner.

The levers 23 are provided with angular extensions 29 having upstanding rollers 30 projecting into the cam groove 31 of the cam member 28. While the speed of the gear 9 will be constant (for a continuously rotating forming machine), the speed of each takeout arm 20 will vary during its revolution at the points and to the extent desired. Such variation is obtained by the proper shaping of the cam groove 31.

Coincident movement of the tongs with the ware and in the mold path may be provided for any desired time, preferably sufficiently long for the tongs to engage the neck or projecting portion of the article in the mold, for the mold then to open and for the tongs then at least to commence the movement of the ware away from the mold. This is accomplished according to the present invention in two ways, first by the angular movement of the. tongs carrying member 15 with respect to the tong arm 20 and slide 17 about the axis of the pintle 18. For this purpose, means are provided for moving the tongs carrying member 15 in both directions with respect to the slide 1'7 by which they are carried.

In the embodiment of the invention shown, the

pintle 18 is rigidly connected to the tongs carrying member 15 and is journaled in projections of the slide 17. One end of the pintle 18 is turned over as illustrated at 32 (Fig. 2), and to this end is connected one end of a tension spring 33, the other end of which is secured to a pin 34 threaded into the slide 17 and passing through a slot 35 in the guideway 19 in which the slide 1'7 moves. The spring 33 constantly tends to urge the tongs carrying member 15 and the tongs carried thereby to the position shown at the right in Fig. 2, in which the article is carried by the tongs 10 with its longitudinal axis substantially vertical. For moving the tongs angularly about the axis of the pintle 18, the tongs carrying member 15 is provided with a downward extension 36 at the lower end of which is a cam roller 3'7. A suitably shaped cam member 38 is secured to the cam 28 as illustrated in Fig. 2. Thus the tongs 10 will be moved from their horizontal position, as seen at the right in Fig. 2, to their inclined position, seen at the left 'in that figure, when approaching the takeout zone, and maintained in that position during their passage through the zone. The cam roller 3'7 is maintained against the cam 38 and the tongs 10 returned to their horizontal position by the action of the spring 33. By properly shaping and locating the cam 38, the tongs 10 are caused to assume the proper angular position with respect to the arm 20 to'engage the neck portion of a bottle or other article in the mold, as illustrated at the left in Fig. 2.

Radial movement of the slide 1'7 to maintain the tongs in coincidence with the mold path the required length of time is controlled by a stationary cam 39 in conjunction with the revolving movement produced by the cam track 31, the resultant of these movements being the coincident movement of the tongs with the ware.

The cam 39 engages rollers 40 mounted on suitable studs extending upwardly from the slides 1'7. The slides 17 are provided with threaded studs 41 extending radially inward of the arms 20 and passing through webs 42 connecting portions of the arms 20. Intermediate the webs 42 and the slides 1'7 and surrounding the studs 41 are compression springs 43. Determination of the limit of the outward movement of the slides 17 is effected by a pair of lock nuts 44 threaded on the studs 41 and adapted to engage the inner sides of the webs 42.

As the tongs approach coincident movement with the mold, they are first moved upwardly to their angular position illustrated at the left in Fig. 2 by the engagement of the rollers 37 with the cam 38. It is then necessary to open the tongs and thereafter to maintain them in open position until they are ready to beclosed' in engagement with the ware after being lowered on opposite sides thereof. The opening of the tongs is effected by the operation of the intermeshing gear segments 45 suitably secured to or formed as a part of the tong arms 12, a cam 46 being provided to operate the crank arm 4'7 which is provided with a roller 48 at its end for engagement therewith. Movement imparted to the roller 48 is transmitted through the arm 4'7 to one of the tong arms 12 and therefrom through the intermeshing gear segments 45 of the other tong arm. The cam 46 opens the tongs prior to their arrival over the ware and holds them open until the arms of the tongs are lowered on opposite sides of the neck or other portion of the ware to be gripped. The spring 16 then closes the tongs about the ware as or before the mold is opened.

Lar ner After the ong or the mold, the takeout continues to advance and is elevated by mocha presently to be described, and the ware is lifted from the bottom plate a before the tongs are moved out or coincidence with the mold path.

ifhe slide operating cam 39 and the tong open ing cam 46 are each removably secured to the bracket 49 by screws so and 51 respectively, so that cams oi difierent sizes and shapes am be substituted thereior to edect the desired ove= inents. it will be noted that screws 51, which secure the cam 46 to the bracket 49, pass through slots 52 disposed substantially tangentially or the takeout structure, and screws so which secure the cam 39 to the bracket 49 pass through slots 53 disposed substantially radially oi the bracket 49. Also the bracket 49 may be angularly adjusted about the shaft 6 by loosening the clamp screw 5% securing this bracket to the shaft and rotatably adjusting the bracket 49 about the shaft 6. in this way the cams 39 and 46 may be adjusted as may be desired to provide for the proper operation of the device, particularly for the proper t no oil the closing of the tongs in the case of cam 46, and for the proper iollow= ing or coincident movement or the tongs with the were in the mold in the case of cam 39.

The ware delivering or discharging station may e located directly opposite the takeout station or at any desired point in the takeout path. The receiving apparatus may be a belt 55 or a revolu= bie or stationary table or any other suitable type of receiver or conveyor which y be actuated either intermittently or continuously and in timed relation to the takeout, and. may be ar= ranged to move the ware away from the takeout path at any desired angle relative thereto.

When delivering the were to a stationary re= ceiver or to a conveyor, as that shown in 55 lifiiOV= ing away substantially at right angles, the takeout is brought substantially to rest over the belt 55 before releasing the were. The cam groove 31, when shaped as indicated between the points 56 and 57, will pet the right hand lever 23 to be moved by the continuously rotating bracket 25 without substantial movement of the corre= spending arm 2o, thus petting the a to be retarded or to remain at rest at the delivery station the desired length of t long enough to efi'ect the delivery of the were to the conveyor 55. from the time the roller 3d reaches the point 5'? of the cam groove '31, a rapid advce oi the takeout arm 20 is produced so as to bring the tongs from the takeout station at the time and at the speed desired to efiect removal of the were from the next succeeg mold, all of which is eflected by the proper shaping of the cam'path 3i and the radial moveme'ntoi the slide 17 in conjunction with the angular movement of the tongs 10 about the axis of the pintle lb.

The opening of the tongs to release the ware at the delivery station is efiected by the movement of an arm 58 into engagement with the roller 48 which, as before stated, actuates the tongs. The 58 is mounted on the upper end of a shaft 59, rotatable in a. bearingmember 60, and is held in inoperative position by a spring 61 tending to move the shaft and the arm 58 clockwise. A pin 62 on the shaft 59 engages an abutment on the bearing and serves to limit the clockwise movement of the arm 58.

Movement of the arm 58 counterclockwise to the operating position shown in Fig. 1 is effected by a second arm 63 secured to the shaft 59 and having a roller 64 in the path of an adiustable when the taheouts are cam as on the gear 9, a separate cam being provided for each of the takeout arms. The cams de'are adjustable to the desired positions and are held by the clamp screws so extending through the slots 67 oi the cams. The tongs opening mechanism lust described may be so positioned as to efiect their opening at any suitable point in the take out path at which it may be desired to discharge the ware.

The talreouts are each lowered twice in a single revolution, first at the takeout station to be closed about the ware, and later at the delivery station to deposit the ware upon the conveyor. The raising and lowering is eflected by providing on the underside oi the gear 9 a cam ring or cir= cular track on resting upon the rollers 69 car= ried by the oppositely disposed bracket to. The tracks is provided with like c saces or de= pressions in which the rollers are located in the position oi the device shown in Fig. 2, these de pressions being diametrically opposed to each other permitting the mechanism to be lowered in the position shown in the drawings and elevating it in other positions, whereby the ware is lifted by. the tongs at the receiving or takeout station and the tongs are raised at the delivery station above the top of the ware just delivered. However, where the conveyor 55 moves continuously, the were may move out from between the tongs before they are raised. During the raising and lowering of the takeout mechanism, the teeth of the gear 9 will slide upon the teeth oi the gear 1 and the end of the shaft 6 will slide in the bearing member '7.

Means are also provided for steadying lower portion oi an article being removed from the mold in the inclined position shown at the left in Fig. 2. Such means include a steadying member, generally indicated at '71 and provided with a resilient or spring clip contactor 72 which will engage the lower portion of an article gripped by the tongs lb. The member 71 is pivoted on a horizontal axis at 73 to a bracket 74 which is suitably secured to the tongs carrying member 15. The end of the member 71 opposite that to which the contactor i2 is attached is extended beyond the pivot 73 and connected to the suitable fixed part of the tongs carrying member 15 by a tension spring 75 which constantly tends to urge the bottom steadier into its operative position with respect to the tongs, at which position it will steady the lower portion of an article gripped thereby. Means are also provided for adiustably limiting the movement of the member ll under the action of the spring 75, that is, the movement of this member toward its operative position. Such means include a shoulder '76 formed on the member ii and adopted to contact with the end of an adjustable stop screw '77 threaded through the bracket 74 and secured in adjusted position by a suitable lock nut 78.

The operation of this bottom steadier is as follows: As the tongs approach the takeout position and approach the path of movement of the were in the mold, which is to be removed, the contactor portion '72 of the steadier will engage the outside of the then closed mold 3, so that as the tongs continue to approach and actually reach the portion of their path in coincidence with the mold, the member 'll'will be moved about its pivot '73 by contact with the outside of the mold, and by extending the spring '75. When the mold 3 is opened, the spring '75 will be effective to move the arm 71 to the position shown at the left in Fig.2, which is the operative position for the steadier. At this position the resilient contactor member 72 will engage and steady the lower portion of the article which is being freed by the opening mold. This engagement will be maintained throughout the transfer of the article to the delivery station, as seen at the right in Fig. 2, thus preventing distortion of the article due to the action of gravity thereon and the support thereof by its neck in an inclined position.
